How can I extract harmonic amplitude value from a double FFT 3D curve?

Yann_Le_Floch

Once you have computed the double FFT as explained in the FAQ “How can I compute the double FFT in the vibro acoustic context in Flux?”, you have to create a 3D curve as follows:

1	Click on 3D curve -> New
2	Select the type “Force as function of frequency and space mode”
3	Select the previously create force curve
4	Select “yes” for limiting the size of the tables

Once the 3D curve has been created, you can extract the harmonic amplitude value by using the command:

ForcesCurve3D['name'].z[0].values[0]

And in order to put this value into I/O parameter, you have to use the command: VariationParameter['test'].formula=str(ForcesCurve3D['name'].z[0].values[0])
